- Sainmhíniú Chromosomen-Mutation, bei der mindestens ein Basenpaar, häufig jedoch mehrere oder sogar sehr viele Basenpaare aus der DNA des betreffenden Organismus entfernt wurden Tagairt "Lexikon der Biologie. Spektrum Akademischer Verlag: Heidelberg, 1999, s. v. „Deletion“, http://www.spektrum.de/lexikon/biologie/deletion/17174 (10.10.2017)"
- Nóta Bei der Deletion kann ein interkalar (in der Mitte) oder terminal (endständig) lokalisiertes Chromosomen- oder Chromatidenstück verlorengehen. Den Verlust endständiger Chromosomenstücke bezeichnet man auch als Defizienz.

- Nóta "It may be as small as a single base or large enough to encompass one or more entire genes. (See also: gene deletion [ IATE:3571263 ]If the deletions occur outside of coding regions, they may have negligible effects on phenotype, unless they affect the expression of nearby genes.Within a coding region, the deletion of exactly three, six, nine or an exact multiple of three nucleotids results in the elimination of one, two, three or a number of amino acids from the encoded polypeptide chain, because three nucleotides is the length of a codon.If the length of the deletion is not an exact multiple of three nucleotides, the mutation shifts the phase in which the ribosome reads the triplet codons and consquently alters all of the amino acids downstream for the site of the mutation (frameshift mutation IATE:1687482 ) Ref: Daniel L.

- Sainmhíniú aberration chromosomique consistant en la perte d’un segment de chromosome Tagairt Dictionnaire illustré des termes de médecine 31ème édition > délétion, M. Garnier & V. Delamare, 2012, Maloine, Paris, ISBN 978-2-224-03257-9 [9.1.2018]
- Nóta "La délétion affecte soit un chromosome («délétion chromosomique»), soit un gène dudit chromosome («délétion de gène» [IATE:3571263 ]). Elle produit une information génétique tronquée et peut entraîner des malformations. (Source: «Délétion, génétique», D.
